Try printing the data from the numpy array before you use it for building the shapefile; verifying that the data is in fact in the numpy array before you use it to build the shapefile. Problem could possibly be how the datarray and dtype map out to one another. print npyarr['LONGITUDE'] print npyarr['LATITUDE'] ... View more

It sounds like you know the formula and the you have the data... What is preventing you from from putting your formula into the Field calculator? Perhaps it's that your intersection points are separate rows in your table and you need to marry them together to do the calculation? if this is the case you can run a summary statistics tool on your points to get the min value and and max value from your elevation field ,grouping them (Case) on your station line identifier. from there it should be easy to just run the field calculator on your two fields. ...

I suspect the issue is with the SearchCursor not being disposed of on completion of it's duties. if you aren't preceding the search cursor with a "with" like this: with arcpy.da.SearchCursor(fc, fields) as cursor : then you'll need to be sure to do del on the variable assigned to the cursor. like this cursor = arcpy.da.SearchCursor(fc, fields) for row in cursor:      ... del cursor you can also try in the same script simultaneously to get the count using arcpy.GetCount_management(fc) to see if the issue is with the cursor or with the connection. here's a link to the getcount_management help page: ArcGIS Desktop ...
